Specification of Letters Patent.

Patented Apr. 27, 1915.

Application filed March 30, 1914. Serial No. 828,277.

' To all whom it may concern.-

Be it known that 1, WILLI M AUs'rIN, residing at Scranton, in the county of Lacka-i wanna and State of Pennsylvania, have invented certain new and useful Improvements in Track-Stops, of which the following is a specification. Y

My invention is an improved track obstruction or stop for use in automatic train stopping systems and the like, and the invention', while of more or less general application, is primarily designed for use in connection withthe train stopping system, which forms the subject matter of my application for patent filed March 1 0, 1914,

Serial Number 823,714. In 'train stopping systems wherein a controlled track obstacle is engaged by a trip lever on the train, it is necessary to so design: the parts" as to reduce the liability of breakage or disarrangement, to the minimum.' Track stops require to be strongly and durably constructed, constructed as simple as possible, and arranged to gravitate to the operative or danger position in case .of any disarrangement or breakage in "the mechanism or its connections. It is also necessary to protect the stop and its operating mechanism from the weather so that itnmay be free .from disablement due to climatic conditions.

My invention, therefore, primarily has for its object to provide adevice which will fultil the requirements as nearly as may be.

Generally, the invention comprises standards or supports on which a substantially U-shaped stop arm is mounted to gravitate to the horizontal orhdanger position, or be held up at anangle of 45 degrees or thereabout in the safety or non-operative position, 'by the action of electro-magneticdevices suitably operatively connected in the block circuit.

The stop arm is partly counter-balanced and is covered by a water shed housing which, except when the arm is in the danger or operative position, completelyhouses the arm; the solenoidal magnets which hold the directly connected thereto or a countershaft may be interposed, if desired, in the connection.

The invention .also includes those novel details of construction, combination and arrangement of parts, all of which will be arm upare either housing 6.

first fully described and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which Figure 1 is a side elevation and part section of the invention, showing its relative location to the signaling semaphore in connection with which it may be employed. Fig. 2 is a top plan view of the same. Fig. 3 is a horizontal section on the line 3-3 of Fig. 1. Fig. l is an enlarged horizontal section on the line'4.4 of Fig. 1. Fig. 5 is a vertical cross section on the line 55 of Fig. 4. Fig. 6 is a vertical longitudinal section and part elevation showing the invention adapted for use on overhead structures. Fig. 7 is a horizontal section on the line 7-7 of Fig. 6, looking in the direction of the arrow. Fig. 8 is a horizontal section on the line 88 of Fig. 6. Fig. 9 is a side elevation showing the invention adapted for use in sub-way structures.

Referring now to the accompanying drawings, in which like numerals and letters of reference designate corresponding parts in all of the figures, 1 represents the standards or supports which are vpreferably made tubular and are provided with chambered portions 2 to receive the electromagnets 3. The magnets 3 are preferably of the sole noidal type and have cores 4 that serve as armatures and are connected by rods 18 with cranks 16 on the stub shafts 13 on which the U-shaped stop arm 9 is keyed. 1

At the top, the standards '1 have flanges 5 by means of which the water shed housing 6 is held in position, the housing 6 having a portion 7 removed, so that when the arm 9 is in its horizontal or active position, the front face 10-11 will be exposed to contact by the train carried arm (not shown). The moving of the arm 9 to the horizontal position is arrested by any suitable stop, for instance stops 8 that may be provided on the The arm 9 is of the substantial U type and has its bend formed by the beveled faces 11 and the front face 10 so as to assure an easy operation of the train carried member when it comes in contact with the stop arm.

The stop arm 9Shas rearward extensions 1' 19 to receive adjustable counter-weights 20 whereby the arm may be partially counterweighted, but not enough to prevent the arm from gravitating to the horizontal position when the magnet 3 is denergized. The arm 9 is also provided with bosses 12, to receive the stub shafts 13, and keys 14 to key the arm to the stub shafts. Each stub shaft 13 has a crank 16 which connects, by a con necting rod 18, with the core 41 of the respective operating magnet 3, and suitableantifriction bearings 15 are provided in the bearing housing 17 formed in the standard 1 as a part of the same, the bearing housing '17 being suitably closed by plugs 21 to prevent access of moisture.

.22 designates the ordinary type of semaphore support having a magnet chamber 23 and carrying the usual semaphore 24:. I have illustrated the relation of the ordinary semaphore to my stop to show the adaptability of the joint use of the two, without interfering with each other. 7

In Figs. 6 to 8 inclusive, is shown a slight modification of the invention. V

In this form, the construtcion is arranged for use on overhead structures of the bridge p 36 designates the bridge and 37 the supporting towers or standards therefor.

Suspended beneath the bridge 36 are the supporting columns 1 which have flanges 5 to-support the housing 6 and which are provided with bearing members 17 to receive the ends of the shaft 13 on which the stoparm 9 is mounted.

8 designates the stops which correspond .to the stops 8 in Fig. 1.

In this form of the invention, vertical extended columns 25, having magnet chambers 27, are provided to project upwardly from the bridge 36. The magnets 3 are located in the chambers 27 and have their cores or armatures 48 connected, by rods 28, to the cranks 29 on a counter-shaft 30, which is mounted in suitable bearings 31 carried by the upper ends of the standards 25.

The standards 25 also have flanges 26 to support the supplemental housing 35 which includes the arms 32 that carry the adjustable counter-weights 20 and are thus keyed at 34 through their hubs 33 to the shaft 30.

The counter-shaft 30 is also provided with a crank 18 which is connected by a connecting rod 18", that extends through a middle column 39, to the crank 16 on the shaft l3 ,whereby the shaft 13* and the counter-shaft 30 may be moved in unison.

In Fig. 9, is shown a further modification, which is quite similar, however, to the structure shown in Fig. 1, differing therefrom essentially only in the omission of the housing 6 and the provision of a recess or chamber 38, which performs the function of the housing 6 in so far as that function is required in a subway structure.

In operation, the magnets 3 or 3 as the case may be, are connected in circuit with any automatic block system to operate in unison with the indicating semaphore, and upon deenergization of the magnets, the stop arms gravitate to their stop or active position.

From the foregoing description, taken in connection with the accompanying drawings, it is thought the complete construction, operation and advantages of my invention will be readily understood by those skilled in the art to which it appertains.
